Structured Data in the Cloud
The Wolfram Language allows structured data consisting of nested lists and associations to be stored persistently in the cloud, and to have parts that are directly manipulated in place in the cloud. Cloud expressions allow for persistent mutable structures to be created in the cloud.
CreateCloudExpression — set up a persistent cloud expression
CloudExpression — symbolic handle to a cloud expression
DeleteCloudExpression ▪ CloudExpressions ▪ FileSize
Operations on Cloud Expressions
obj[part,…] — retrieve the value of a part
obj[part,…]=val — set the value of a part
Unset — remove the value of a part
Get — get the complete value of the cloud expression
Put — put a complete value for the cloud expression
AppendTo ▪ AssociateTo ▪ Increment ▪ AddTo ▪ ...
Cloud Expression Control
PartProtection — what parts to protect from resetting
Permissions — control of access etc.
SetPermissions ▪ ClearPermissions ▪ SetOptions
Unstructured Data in the Cloud
CloudSymbol — a symbol whose value is stored in the cloud
CloudObject — general handle to an expression in the cloud
Databin — a sequentially filled databin
